• Q: What is the difference between open cell
  foam & closed cell foam?
  A: Open cell foam is a soft, 0.5 LB foam that expands 100x's its volume when applied. It is a soft foam (much like the foam found in bed pillows) and has an R-value of R4 per IN and is used about 90% of the time for new construction. Open cell foam is a 99% air barrier and therefore stops 99% of air borne water (i.e., water vapor). Closed cell foam is a very dense 2.0 LB foam that cures to a very hard material. It is both an air barrier and a moisture barrier with an R-Value of R7 per IN of thickness. Please see the attached article: "Foam Selection: Closed Cell or Open Cell?" for more in-depth information.
• Q: My house is finished with some insulation, is there any way that I can insulate the walls now?
  A: Seal It has recently taken on a new line of wall injection foam called Tripolymer Foam, that is specially formulated for insulating walls by injecting the foam from either the outside or the inside of the house, and whether there is existing insulation in the walls or not. Tripolymer foam is fire proof and has an R-value of R5.1 per IN of thickness and provides an air seal. So old houses that have 2 IN X 4 IN wall construction can be insulated to an R19 and be draft free. There is an excellent video of the process shown on www.injectionfoam.com.
• Q: I don't have to ventilate my attic?
  A: No, foam insulation can be used with either vented or unvented roof configurations. In an unvented roof the foam is sprayed directly on the underside of the roof between the rafters. This direct insulating approach makes it unnecessary to vent any of the roofs or the eave soffits, and thus avoids any moisture, draft, or critter problems that may occur with vented roof systems over time. Most importantly, the foam insulation will air seal the roof, thus eliminating any air infiltration, preventing heat loss in the winter time, and alternatively preventing heat gain during the summer months. Please see the attached article: Unvented Roofs for further information.
• Q: Is your insulation "green"?
  A: The short answer is "yes". There are many different definitions of what "green" is, which can mean different things to different people and depending upon the context. There is an excellent in-depth article attached written expressly for closed cell foam, but also applies to either open cell foam or Tripolymer injection foam: "Is Spray Foam 'GREEN' Insulation?"
• Q: Will spray foam insulation work as a sound barrier?
  A: SPF reduces airborne sound making the home acoustically tighter and more private from room to room. Spray foam insulation is a quiet design built right in to protect you against unwanted noise.
• Q: The EPA has rated IAQ (Indoor Air Quality) as one of their top 5 Concerns; how does foam insulation help this serious issue?
  A: Spray foam insulation is specially formulated with an anti-microbial ingredient to inhibit mold, mildew & bacterial growth. In addition, SPF (spray polyurethane foam) insulation creates a complete, or near complete air barrier to minimize airborne moisture infiltration and condensation across the building envelope and works with a properly designed HVAC and ventilation system to help control humidity and optimize indoor air quality. Please see the attached article: "Mold, Dust & Allergens" page for more information on this concern for homeowners and their families.
• Q: I can't afford to foam my whole home, now what?
  A: We @ Seal It Insulation understand the costliness of our product and are willing to work with you in order to most cost effectively insulate your home. We have dealt with a number of clients who could only afford to insulate one area in need at a time. Since homes loose 60-70% of heat through the attic this would be the most important space to insulate. After that would be the basement and then your walls. Please visit our "Homeowners" page to see additional information about available tax credits and H.E.L.P. loans for further assistance.
• Q: Will spray foam insulation sag or settle over time?
  A: If SPF is installed correctly it will not sag or settle at all & is guaranteed for the life of your home.
